ACCOUNT BOOK.

Application filed December 22, 1926. Serial No. 156,486.

The present invention relates to improve-V ments in account books andhas for its primary object to provide a structure which may be embodiedin bound as Well as loose-leaf books to providea convenient index.

A further object of the invention is the provision of an index for booksembodying removable index strips whereby the indexing of the leavesmaybe conveniently'changed.

Another object of the invention is the pro* vision of an indexconstruction of the above character which is simple of construction,efiicient for the purpose intended and 'Which can be manufactured at arelatively low cost.

Other objects and advantages of the invention will become apparent asthe description progresses.

In the accompanying drawings forming a part of this specification and inwhich like reference characters are employed to designate correspondingparts of the same:

Figure 1 is a plan vieiv of a book constructed according to myinvention,

Figure 2 is a vertical transverse sectional view taken on the line 2Q ofFigure 1,

Figure B is a fragmentary perspective view of a portion of a bookconstructed in accordance with my invention, and y Figure 4 is anenlarged transverse sectional view taken on the line lf-t of Figure 1.

Referring tothe drawings, wherein for the purpose of illustration isshown the preferred embodiment of my invention, the numeral 1()designates the front cover board of a conventional type of book arrangedin opposed position to a book cover board 11. These cover boards arepreferably formed of rigid material suoli as cardboard. Secured betweenthe front and rear cover boards are a plurality of paper sheets 12, inthe present embodiment these sheetsbeingruled vertic ally,to definecolumns, as indicated at 13. The cover boards and sheets are preferablyformed with perforations 14 near one vertical edge to accommodate snapfasteners 15 or other removable fastenings, thus providing a binder ofsubstantially loose-leaf construction permitting replacement of thesheets when desirable.

As clearlyshown in Figure 2, the ruled blank paper sheets 12 terminateconsiderably below the upper edges of the front and rear cover boards 10and 11, for a purpose which Will become apparent as the descriptionprogresses.A

The essential feature of my present invention resides in the provisionof a division sheet or board 15 preferably of heavier construction thanthe usual Writing sheet and similar in marginal contour to the formationofthe front and back cover boards. AFrom this construction, it will beapparent that the upper longitudinal edge of the division sheet Y 15will be parallel with the upper edges of the front and back coverboards. A series of spaced perforations 16 are formed adjacent the upperedge of the sheet 15 as indicated in Figure 3. y

Formed so as to be positioned against each side of the divider sheet 15adjacent the upper edge are index strips 17 of paper or any othersuitable material and having openings 18 which register with theopenings 16 in the division sheet. The index strips 17 are marked withvertical lines 19 adapted to extend in 'vertical alignment with thelines 1375 of the ruled sheets 12. Suitable designations are markedonthe index strips 17 in longitudinal positionbetween the lines 19 so asto form designation headings above the columns of the blank sheets.

The index strips are secured in position on the division sheet by meansof a longitudinal clip member 2O preferably formed `of celluloidor'similar transparent material and extending the entire length of theupper edge of the division sheet to overlap the index strips, the yclipmember 20 being U-shaped in cross-section and fitted over the Upper edgeof the division sheet and the index strips 17 andV formed Withtransversely alined openings 21 adapted to register with the openings 18formed in the index strips. The clip member 20 is preferably ofresilient construction so as to normally retain the index strips 17tightly against the faces of the division sheet, the said clip memberand index strips being secured in position by suitable snap Vfasteners.Thisk will permit convenient removal and replacement of the index strips17 to vary the index headings when necessary.

While my improved index structure has been illustrated in applicationupon a detachable form of binder it is readily apparent that thev samemay be effectively employed upon permanentlyrbound volumes as Well asloose leaf binders and any number of Vdivision sheets may be employed ineach'volume. This structure presents a replaceable index 'of a durablenature designed to obviate the mutilation of the index headings by thecustomary use of the book. Furthermore, the index headings will beprotected from mutilation and soilin by the provision of the clip memberwhic entirely covers the index strips. Y

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as the preferred example of the same and thatvarious changes as to the shape, size and arrangement of parts may beresorted to Without departing from the spirit of the invention or thescope of the subjoined claims. Y

Having thus describedl my invention, I claim: Y

l. A book of the character described'comprising front and back coverboards, a plurality of sheets secured at one of their side edges betweenthe cover boards, a division sheet disposed between certain of the irst`mentioned sheets, and an index strip removably secured to the uppermarginal portion of said division sheet. Y

2. A book of the character described comprising :tront and back coverboards, a plurality of blank sheets retained at one of their side edgesbetween the cover boards, a division sheet disposedV and retainedbetween certain of the blank sheets, and index strips, removably mountedon the upper marginal portion of said division sheet.

3. An account book comprising front and back cover boards, a pluralityor" blank sheets secured at one of their side edges between the coverboards, a division sheet' disposed between certain of the blanksheetsand having its upper margin projecting beyond the upper edges ot thelatter, and index strips removably secured to the upper projectingmargin oi the division sheet.

4. In an account book, in combination, a binder including a front and aback cover board, a plurality of blank sheets secured at one of theirside edges between the cover boards, an index including a division sheetdisposedand retained between certain of the blank sheets, index stripsupon the upper edge portion of the division sheet, and a transparentclip member removably fitted over and confining the index strips and thesaid edge ofthe .division sheet.

5. In an account book, in combination, a binder including affront coverboard, a back cover board, a plurality of blank sheets secured betweenthe cover boards, an index including a division sheet secured betweencertain of the blank sheets and having one edge projecting beyond thecorresponding'edges of the blank sheets, a pair of index strips disposedagainst oppositesides'of the projecting edge of the division sheet, aclip member embracing the index strips and the said edge of the divisionsheet, and separable fasteners exten ding through the clip member. theindex strips, and the .division sheet and detachably connecting the clipmember in position.

6. ln an account book, front and back cover boards, a division sheetarranged between the same and constituting means for separating, intogroups, blank record sheets arranged between the cover boards, fastenersremovably fitted through the said cover boards and divisionv sheet forconnecting the same in assembled relation and constituting, also, meansfor removably retaining blank record sheets, an index strip disposedagainst one marginal portion ot the division sheet, and meansren'iovabiy securing the index strip to said mar? ginal portion of saiddivision sheet.

In testimony whereof he has affixed his signature.
